9030DS单色仪

名称: 9030DS单色仪

型号: 9030DS

品牌: Sciencetech

  • 详细信息

9030DS包含两个以减法模式串联放置的100 mm扫描单色仪。带通由中间狭缝的宽度决定,但是9030DS的净输出色散为零,因为单色仪是光学耦合的,因此第二个光栅的色散抵消了第一个光栅的色散。这会导致输出端口处的波长均匀化-没有光谱,只有一个未分散的狭缝图像-这使该设备可以用作可调带通或陷波滤波器。

 

在双重单色仪中,可以大大减少各种杂散光,在9??030DS中,通过使用凹面全息光栅,可以进一步减少杂散光。它是杂散光有问题的应用的理想选择-可能存在强烈散射的背景,例如在光谱辐射法,拉曼光谱或太阳辐射的UV测量中。

 

此价格包括一组标准狭缝,其中包括标准中间(倒置)狭缝,但不包括光栅。我们还提供定制的中间(倒置)缝;请与我们销售人员联系。

9030DS - Double Subtractive 0.1 m Compact Monochromator

The 9030DS consists of two 100 mm scanning monochromators placed in series in subtractive mode. Bandpass is determined by the width of an intermediate slit, but the 9030DS has a net output dispersion of zero because the monochromators are optically coupled so that the dispersion of the second grating cancels that of the first. This leads to homogenized wavelengths at the output port - there is no spectrum, only a single undispersed slit image - which allows the unit to act as a tunable bandpass or notch filter.

 

Stray light of all sorts is drastically reduced in a double monochromator, and in the 9030DS it is further minimized by the use of concave holographic gratings. It is ideal for applications where stray light is a problem - where there may be a strong scattered background, such as in spectroradiometry, Raman or UV measurements of solar radiation. 

 

This price includes a standard set of slits including a standard intermediate (inverted) slit, but does not include gratings. We also offer customized intermediate (inverted) slits;
